14C 0 2 Fixation, Amino Acid Pools, Salinity, Marine Diatoms The marine diatoms Bellerochea yucatanensis and Thalassiosira rotula were grown at different salinities (20/25, 35, and 40/45%o salinity (S), respectively) under normal air (0.035 vol.% C 0 2). No significant variations in the percentage of gross photosynthetic products (e.g. total amino acids, sugar phosphates) were found as a functi...

in order to study the effects of various levels of protein in diet based on total and digestible amino acids on performance and carcass traits of broilers, an experiment was conducted as a completely randomized design with 288 broiler chicks from cobb 500 strain in 6 treatments, each treatment consist of 3 replicates with 16 chicks per replicate. treatments were the diets as follow: 1) diet for...

The strong acids that are required for complete hydrolysis of proteins destroy some amino acids, such as tryptophan, asparagine, and glutamine. Other amino acids are destroyed to a lesser extent or in certain cases are released incompletely from peptide linkage. It is evident that these difficulties, as well as others, could be overcome by employing proteolytic enzymes as the sole agents for hy...

Punch, J. D. (University of Minnesota, St. Paul), J. C. Olson, Jr., and J. V. Scaletti. Amino acid utilization by Alcaligenes viscolactis for growth and slime production. J. Bacteriol. 89:1521-1525. 1965.-The ability of Alcaligenes viscolactis to utilize amino acids in a basal salts solution (K(2)HPO(4), KH(2)PO(4), MgSO(4), MnSO(4), FeSO(4), NaCl) was studied. Of 27 amino acids, only l-asparag...

Protein N-glycosylation requires the presence of asparagine (N) in the consensus tri-peptide NXS/T (where X is any amino acid, S is serine and T is threonine). Several factors affect the glycosylation potential of NXS/T sequons and one such factor is the type of amino acid at position X. While proline was shown to negatively affect N-glycosylation, the nature of other amino acids at this positi...

Recently several complete cDNAs encoding the Narcissus tazetta lectins (NTL) were cloned. The sequence analyses of the cloned DNAs reveal that there are at least three unidentical positive clones for NTLs. The primary structure of the three NTL clones contains a mature polypeptide consisting of 105 amino acids and a C-terminal peptide extension beyond the C-terminal amino acids Thr-Gly. There a...

An alternate medium consisting of sugarcane juice (SJ) (Saccharum spp.) and chicken feather peptone (CFP) was employed for microbial synthesis levan. SJ has considerable amounts vital minerals, vitamins, amino acids in addition to its major constituent, sucrose. Meanwhile, CFP is also a rich source essential nutrients such as acids, micro macro elements. Amino present CFP, glutamic acid, argini...

Background and Aims: Amino acids have different effects on the growth of some dermatophytes. Some may increase whereas others maydecrease their growth. The concentration of some amino acids is also an important factor for their effects. Materials and Methods: To investigate the effects of L-amino acids on the growth of six species of dermatophytes including Epidermophyton floccosum, Microspor...

Amino-acid neurotransmitter system dysfunction plays a major role in the pathophysiology of depression. Several studies have demonstrated the potential of amino acids as a source of neuro-specific biomarkers could be used in future diagnosis of depression. Only partial amino acids such as glycine and asparagine were determined from certain parts of rats' brain included hippocampi and cerebral c...
